I'm looking to pour a 10'x14' 6" slab for a garden shed (roughly 2.5 yards of concrete). One bid would bring a concrete truck, one write get a bunch of quickrete bags (~120) and rent a mixer. The largest rental mixer would take about 8 batches to do this job. The plan is to use 6" remesh in the slab.
Would doing that many batches/partial pours cause any problems with the slab structure? What's the best way to do the partial pours - do an eighth of the area per batch, full thickness? Spread each batch thinly over as much as it will cover? Our just plop it in wherever?
